If it still leaks after cleaning, it was never a cleaning problem.
Overflow that survives a clean means the gutter itself has failed: rust-through, wrong fall, failed joins, or the internal box gutters hiding behind your villa's fascia. Repairs start from $150; new continuous spouting runs $45 to $85 per metre. And box-gutter conversion is specialist work, not a handyman job.
Is this your stream?
Persistent leaks after cleaning, visible rust, sagging sections, overflowing in moderate rain, or a building inspection flagging internal box gutters. This is trade work: spouting specialists and roofers, not cleaners.
Debris blockage with no damage is a standard clean at $150–$300. Tired of cleaning under heavy tree cover? Gutter guards are the cheaper long-term lever than repeated repairs on neglected gutters.

Choose by situation
PKWS specialises in internal-to-external conversions on older Auckland homes; Continuous Group lists internal gutter replacement as a specialty. Cleaning will never fix a corroded box gutter.
Roofing Expert publishes repairs from $150, new spouting at $45–$85/m and full replacement at $2,500–$8,000. Gutter Repair Auckland publishes its repair cost guide. Benchmark any other quote against these.
JP Franklin Roofing assesses gutters as part of the roof system, including flashing and asbestos roof management. Right when overflow might be a roof problem wearing a gutter costume.
Custom Fascia and Spouting handles both in one job, and Continuous Group's long-run system removes most leak-prone joins. Check fascia condition before new spouting goes on.
Common mistakes
Cleaning a leaking box gutter and calling it fixed: internal box gutters corrode from the inside and overflow into wall cavities. Cleaning is a stopgap. Conversion to external spouting is the permanent fix, and it is specialist work.
Patching rusted spouting repeatedly: once rust-through starts, patches buy months, not years. A section replacement at $40–$80 per metre is often cheaper than the third callout for sealant.
Assuming the gutter is the whole problem: overflow can come from undersized downpipes, wrong fall, or roof flashing issues. A roofer's assessment (JP Franklin, Roofing Expert) covers the whole rainwater path, not just the trough.
Choosing PVC patch repairs on metal spouting without asking about compatibility: mixed materials and poor joins are where future leaks start. Continuous long-run spouting removes most joins entirely.
Not checking the fascia while the spouting is off: replacement spouting goes onto the fascia, and rotten fascia under new spouting is a hidden failure. Firms doing both (Custom Fascia and Spouting, Continuous Group) handle it in one job.
Comparing per-metre quotes without the scope: $45–$85 per metre for new spouting varies with profile, material, height access and whether downpipes and fascia work are included. State storeys and access when you quote.
FAQ
How much does spouting repair cost in Auckland?
Published Auckland guidance: minor repairs like sealing leaks or replacing brackets run $150–$400, more extensive sectional repairs $300–$1,200, section replacement $40–$80 per metre, and full replacement $2,000+ (Gutter Repair Auckland's guide). Roofing Expert publishes new spouting at $45–$85 per metre and full-house replacement at $2,500–$8,000.
What is an internal box gutter, and why is it a big deal?
Many older Auckland villas and bungalows have gutters hidden behind the fascia rather than mounted externally. They corrode from the inside, overflow into wall cavities, and show up in building inspections. If cleaning does not stop the leak, the fix is conversion to external spouting, a specialist job for firms like PKWS or Continuous Group.
Repair or replace?
Localised leaks, loose brackets and minor sagging are repair territory ($150–$400). Rust-through, repeated patching, wrong fall and corroded box gutters point to replacement: $40–$85 per metre depending on material and access. A repair-honest operator will tell you which side of the line you are on.
What is continuous spouting?
Long-run metal spouting rolled on-site to your home's measurements, with no joins except at corners. Fewer joins means fewer leak points. Continuous Group pioneered the system in NZ over 30 years ago and has installed on 300,000+ homes.
What should I ask before booking?
State storeys, access, the symptom (leak, overflow, sag, rust) and the home's age. Ask whether the quote includes downpipes, fascia checks and GST, whether the operator handles internal box gutter conversions if your villa has them, and what warranty covers materials and workmanship.
Minor leaks go to Gutter Repair Auckland or Roofing Expert (both publish pricing, repairs from $150). Full replacement goes to Continuous Group's long-run system or Custom Fascia and Spouting at $45–$85 per metre. Villa box gutters go to PKWS or Continuous Group for conversion, and anything that might be a roof issue goes to JP Franklin for a full assessment. State storeys, symptoms and the home's age when you quote, and check the fascia before new spouting goes on.
